Questions
Light of wavelength 5.0 x 10-7 m falls on a pair of narrow slits separated by a distance (2d). The interference pattern on a screen placed 2.0 m away shows that there is darkness at the position exactly opposite to each slit. The separation between the slits
detailed solution
Correct option is B
we know that β=λD2dHere, tho distance between two dark fringes is equal to the separation between the slits i.e β =2d(2d)=λD(2d) or (2d)2=λD or (2d)=(λD) so (2d)=5⋅0×10−7×2⋅01/2=10−3m=1⋅0mmTalk to our academic expert!
